So one of my favorite things about this game is the companion system, and I recently subbed to get access to the new(er) expansions in the game. Now I've seen it said here and there that there are new companions within these expansions, as well as "returning" ones....but that leads to a question. If I start the expansion story, do my companions come with, or do I loose them and have to build a new crew? If the latter case, what companions return, and when?
